======== Required information ====
Hi Admin iReadMail!
I set up SMTP using service of Amazonaws and have information of Relayserver such as: relayhost: email-smtp.us-east-2.amazonaws.com:25
IAM User Name: domain.net
Smtp Username: AKIAIA3
Smtp Password: xxxxxx
Then I follow the instruction
http://www.iredmail.org/docs/relayhost.html
In /etc/postfix/main.cf
and add the below line

#SMTP Relay
relayhost = [email-smtp.us-east-1.amazonaws.com]:25
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password
smtp_sasl_auth_enable = yes
smtp_sasl_mechanism_filter = login
smtp_sasl_security_options = noanonymous

Then I create a file /etc/postfix/sasl_password,
in this file I add Relayserver and user pass: [email-smtp.us-east-2.amazonaws.com]:25 AKIAIA3:xxxxxx

Then I restart, at the final step, I login Mysql:
mysql>  USE vmail;
INSERT INTO sender_relayhost (account, relayhost) VALUES ('domain.net', '[email-smtp.us-east-2.amazonaws.com]:25');

Eventhough I follow all steps above but I can not send mail successfully, my inbox is shown in the picture

This is not required since you have global relay (relayhost=). Please remove this sql record and try again.

Does Amazon ask you to use port 25 or 587?

Run "postmap hash:/etc/postfix/sasl_password" first after you modified this "sasl_password" file, then try again.

Re: Error in set up Relayhost using SMTP of Amazonaws

If Postfix tries to connect to Amazon server, it will log the Amazon server name or IP address in Postfix log file (/var/log/maillog). Please try again and check Postfix log file.

Port 10026 is (part of) Amavisd service, and it doesn't require TLS or SSL at all. I'm confused why it requires TLS in your case.

What Amavisd and Postfix settings did you change?

Re: Error in set up Relayhost using SMTP of Amazonaws

The problem is port 10026 on YOUR server, not Amazon.

Did you define port 10026 in /etc/postfix/master.cf? If YES, please comment it out, then restart Postfix, and make sure you have setting below in /etc/amavisd/amavisd.conf:

$inet_socket_port = [10024, 10026, 9998];

I did comment as in the attached picture: content_filter = smtp-amavis:[127.0.0.1]:10024 in file  /etc/postfix/master.cf.

then I check /etc/amavisd/amavisd.conf follow your instruction. but still I can not send email successfully.  file maillog:

Re: Error in set up Relayhost using SMTP of Amazonaws

There's another one in /etc/postfix/master.cf like this:

    -o content_filter=...:10026

BTW, why you comment out content_filter parameter? You will lose spam/virus scanning if you comment it out.

The solution to your issue is making sure you have "$inet_socket_port = [10024, 10026, 9998];" in Amavisd config file, then port 10026 is available and mail flow should be fine.

Thank you for your prompt reply

I comment line  #o content_filter=smtp-amavis:[127.0.0.1]:10026 in file /etc/postfix/master.cf

Why it tried to access to port 10024 now? Comment out 'content_filter' in /etc/postfix/main.cf and restart postfix service.

Next time, please read the log first.

Thank you for your prompt reply.
I comment line #content_filter = smtp-amavis:[127.0.0.1]:10024
Do you know this error comes from iRedmail or Amazonawss?

Re: Error in set up Relayhost using SMTP of Amazonaws

It's an error on your side. Please show us output of command "postconf -a". also, try different port number in Postfix "relayhost =" setting, e.g. 25, 587. You should check Amazon doc to make sure you're using correct port number.

This is the result of the command:
[root@mail ~]# postconf -a
cyrus
dovecot
I also try port 25, 465 or 587, then still can not send email
can we use another method instead of amazonaws to avoid sending spam email
